If you do not have the tools for measure, you can index mark the pinion flange nut so it goes back to the original position. That usually gets you back to where it was before, but not a true torque spec procedure.

This is the way I do it.
And I have an inch-pound torque wrench.

I only use the torque pre-load procedure if I change a pinion bearing.
I have one of those old Snap-On Torque-O-Meter from the Navy...kinda cool tool.

I have a Differential out of a W126 that Iam going to install in my 85 300D. I need to use the flange off the 300D and install on the W126 Diff.

The 123 has a smaller flex disc than the 126.

I purchased a new pinion shaft nut and oil seal. thought this is a good time to replace it.

I bought a new nut figuring using the old nut it wouldn`t stake in properly and might loosen up.
So how do I get the proper torque with the new nut?

also how would I use the inch pound to determine the torque preload. I have never done this before. splain it to me . Iam a dummy in this dept.

I read another thread where the guy said the nut is a little more that finger tight. something like 0.75 in lb.
